Product Description:
Kryption gas is odorless, colorless, tasteless, nontoxic, monatomic and chemically inert gas. Krypton gas is principally shipped and used in gaseous form for excimer lasers, light bulbs, window insulation, ion propulsion, medical applications and Research and Development laboratory research.
 The package is 4L- 50L cylinders.

Usage Typical Application:

In the semiconductor process:

Krypton gas is used in medical, light bulb, electronic, and excimer lasers and for ion propulsion. Tantalum has a high molecular weight and is used as a window insulation to reduce heat loss due to convection between the glass sheets.

In electronic industry:

The light spectrum of XENON is much wider than NEON or KRYPTON. Due to its high brightness, it is used in high-intensity aviation lamps, high-efficiency incandescent bulbs on automobiles, plasma display panels, operating rooms and UV lasers.

Application: 1.In the semiconductor process xenon is used in medical, light bulb, electronic, and excimer lasers and for ion propulsion. Tantalum has a high molecular weight and is used as a window insulation to reduce heat loss due to convection between the glass sheets 2.In electronic industry The light spectrum of XENON is much wider than NEON or KRYPTON. Due to its high brightness, it is used in high-intensity aviation lamps, high-efficiency incandescent bulbs on automobiles, plasma display panels, operating rooms and UV lasers

Advantage:

1. Our factory produces Krypton from high quality raw material,besides the price is cheap.
2 .The Krypton is produced after many times procedures of purification and rectification in our factory.The online control system insure the gas purity every stage.The finished product must meet the standard.
3. During the filling, the cylinder should firstly be dried for a longtime(at least 16 hrs), then we vacuumize the cylinder, finally we displace it with the original gas.. All these methods make sure that the gas is pure in the cylinder.
4. We have existed in Gas field for many years, rich experience in production and export let us win customers' trust. They satisfy with our service and give us good comment.

Since the establishment of our company, it has received universal praise by virtue of good reputation, high quality and perfect after service.
